Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed, ...

One factor that makes glioblastoma cancers so difficult to treat is that malignant cells from the tumors spread throughout the brain by following nerve fibers and blood vessels to invade new locations. Now, ...

Move over, nanotechnologists, and make room for the biggest of the small. Scientists at the Harvard's Wyss Institute have built a set of self-assembling DNA cages one-tenth as wide as a bacterium. The structures ...

Despite having a diameter tens of thousands of times smaller than a human hair, nanopores could be the next big thing in DNA sequencing. By zipping DNA molecules through these tiny holes, scientists hope ...

(Phys.org) —U.K. based Oxford Nanopore Technologies has made good on a promise made two years ago to produce an inexpensive genome sequencer that is based on nanopore technology. David Jaffe, with the Broad ...

RNA interference (RNAi), a technique that can turn off specific genes inside living cells, holds great potential for treating many diseases caused by malfunctioning genes. However, it has been difficult for ...

Scientists at UC Santa Barbara have designed a nanoparticle that has a couple of unique—and important—properties. Spherical in shape and silver in composition, it is encased in a shell coated with a peptide ...

(PhysOrg.com) -- Using cutting-edge microscopy techniques, researchers have gained insight into how human mummies can be extremely well-preserved for thousands of years. A team of scientists from Germany and ...

Inspired by tiny particles that carry cholesterol through the body, MIT chemical engineers have designed nanoparticles that can deliver snippets of genetic material that turn off disease-causing genes.

About one in four older adults suffers from chronic pain. Many of those people take medication, usually as pills. But this is not an ideal way of treating pain: Patients must take medicine frequently, and ...
